Tomography is a method used for X-ray photography. Further, the methods have to be applied to rearrange picture parts, enhance color separation, and improve quality.Įxample: Medical applications use image processing techniques for picture enhancement, in tomography, and in simulation operations. To apply image processing techniques, the first step is to digitize the picture into an image file. Image processing is defined as a technique to enhance raw images captured using various vision sensors for various applications such as medical imaging, the film industry, intelligent transportation, etc. Image and its pixels Explain Image Processing The figure below is showing an image and corresponding pixels of a point The value of pixel has ranged from 0 to 255.ģD animation, modelling, simulation, game development & others A digital image consists of pixels having particular locations and values. If a, b and the values of f are finite, the image is said to be a digital image. The range of ‘F’ at any point of (a,b) is called the intensity of the image at that point. What is an Image?Īn image is represented as a function F(a,b) which is 2-dimensional, where a and b are the spatial or plane coordinates. Techniques that are used in digital image processing are Image editing, Image restoration, Linear filtering, Pixelation, Point feature matching, Principal components analysis, Independent component analysis, etc. Digital image processing is used in projects dealing with classification, feature extraction, pattern recognition, etc. Digital Image Processing contains the processing of images such as reading, analyzing, and manipulating an image, and performing any kind of operation, such as improving the information representation of an image, processing the image data for storage, transmission, and representation. Digital image processing is a process to perform image processing algorithms on digital images.
